>Basic NLP starts with simple techniques like stemming, synonyms, typo correction etc. But many users expect more, e.g. contextual disambiguation or broader synonym/similarity resolution. These users would see a search engine as dysfunctional if it could not even find pages in which a plural form or a spelling variation of a query term occurs. Any morphological variation would already be covered with stemming alone, so this particular point doesn’t speak in favor of more advanced interpretations, does it? Having an path which uses advanced AI powered tools doesn’t necessarily imply one should drop any ability to search with more technical query interface for advanced users. And it’s doubtful big companies wouldn’t have the budget to maintain even two completely distinct tools, would it be required.
